How to Get the 'Who You Gonna Call?' Achievement in Metal Gear Solid 2 HD

To understand how mind-blowing this achievement is for me, it should be known that Metal Gear Solid 2 is one of my favorite games ever made. Like, in the history of video games, this is probably my second favorite game of all time. I know every where secret, item, and Easter egg is in this game. So when I saw the footage for this achievement in the video below, you'll understand why I screamed like a girl.

To get the 'Who You Gonna Call?' achievement, you have to take a picture of the ghost that's haunting the Tanker. I swear it's there. When you're sneaking past the room full of Marines with the two projectors, if you take out your camera and take a picture of the screen, a face will show up in the picture. Also, you may want a change of pants when you view the result.
